Pharmacology

Silver sulfadiazine is a sulfa derived topical broad-spectrum antimicrobial and antifungal cream. It is bactericidal for fungi and Gram-positive and Gram-negative organisms.

Its action is to disrupt both microbial cell walls and cell membranes.

The systemic absorption of silver sulfadiazine varies largely upon how large a body surface area that it is used on. At this time it is unknown if silver sulfadiazine is excreted during lactation.1

Studies show no indication of teratogenic or carcinogenic effects in rats or rabbits.
